International Classification:

G01S 316

US Classification:

342383, 342380

Abstract:

A method for controlling an adaptive antenna array ( ) is provided and includes receiving a plurality of signals, each signal including a series of signal data symbols ( ) and signal non-data symbols ( ) divided into symbol transmission units with the signal non-data symbols ( ) disposed among the signal data symbols ( ) in each unit and each signal related to the other signals of the plurality of signals as reflections of an original signal. The method also includes separating the signal non-data symbols ( ) from the signal data symbols ( ), and comparing the signal non-data symbols ( ) to a set of known non-data symbols. The method further includes determining a set of weights according to the comparison of the signal non-data symbols ( ) to the set of known non-data symbols, the weights to be combined with the signal data values ( ) to limit the effect of interference on the signal data symbols ( ). An adaptive antenna array ( ) is also provided including a weight calculator ( ) including a program which controls the weight calculator ( ) to perform the comparing ( ) and determining steps ( ) of the method discussed above.

International Classification:

H04J 3/06

US Classification:

370338, 370350, 455 412

Abstract:

A method and apparatus for synchronizing a node () within an ad-hoc communication system () is described herein. During operation all nodes periodically broadcast a synchronization beacon for other nodes to utilize for synchronization when a coordinating access point (node) is unavailable. A particular node's synchronization beacon will have an associated “tier” number that is incremented from the tier number of the beacon used to synchronize the particular node. In the absence of an access point, a node that joins the ad-hoc communication system will listen for synchronization beacons transmitted by other nodes. If synchronization beacons are heard, the node will synchronize with a beacon having a lowest tier. The node will then broadcast its own beacon having its tier number incremented from the lowest tier beacon heard.

International Classification:

H04L 12/28

US Classification:

370255, 370254, 709238

Abstract:

Techniques are provided for detecting an increase in congestion in a distributed ad hoc network architecture and transitioning from the distributed ad hoc network architecture to a cluster ad hoc network architecture when a sufficient increase in congestion is detected based on one or more congestion level indicator values (CLIVs). Other techniques are provided for detecting a decrease in congestion in cluster ad hoc network architecture and transitioning from the cluster ad hoc network architecture to a distributed ad hoc network architecture when a sufficient decrease in congestion is detected based on one or more congestion level indicator values (CLIVs).

Abstract:

2-substituted benzimidazoles and methods of preparing the same are disclosed. The compositions may include a compound or salt thereof, a strong acid, and a carboxylic acid. The compositions may exclude a polar aprotic solvent. The compositions may be used to inhibit corrosion of a metal surface in contact with an aqueous system, and provide enhanced protection against corrosion of metals in the aqueous system.

International Classification:

H04W 48/20
H04W 56/00
H04W 48/04

Abstract:

Techniques for controlling or managing uplink access of a UE to a base station using unlicensed spectrum includes signaling an indication of different uplink access constraints so the UE connects to the base station when the UE and/or the uplink direction between the UE and the base station meet the uplink access constraints. The indication may be broadcast in a reference or synchronization signal, e.g., by utilizing unused or undesignated bits. Uplink access constraints may include a threshold distance of UEs from the base station, interference in the uplink direction (which may differ from interference in the downlink direction), etc. Based on the indicated constraints, the UE may determine whether or not to consider the base station as a candidate serving cell for wireless network access. The UE may be an in-flight aircraft and the base station may be a logical cell of a network that provides in-flight connectivity services.

International Classification:

G01N 33/18
G01N 21/64
C23F 11/14

Abstract:

The present disclosure generally relates to methods of measuring benzimidazole-based corrosion inhibitors in cooling water. Methods may include withdrawing a sample of water containing a benzimidazole-based compound from an aqueous system and adding an acid to the sample of water and/or diluting with water. Methods may also include exposing the sample of water to light energy of a selected excitation wavelength and measuring an intensity of emitted light about a selected fluorescence emission wavelength. The intensity of the emitted light may be compared to a standard curve, which can be a plot of fluorescence emission intensity of the benzimidazole-based compound versus concentration of the benzimidazole-based compound. The concentration of the benzimidazole-based compound in the sample of water may be determined from the standard curve.

Abstract:

This disclosure relates to compositions and methods of reducing corrosion using benzimidazoles. The method may include adding a benzimidazole and a halogen to an aqueous system that is in contact with a metal surface. The halogen may be bromine, iodine, or any combination thereof. In some cases, adding the halogen may be optional depending on the substituents on the benzimidazole ring. Compositions are also disclosed that include a benzimidazole, optionally a halogen depending on the substituents on the benzimidazole ring, and optionally a halogen stabilizer.
